It is very natural, moisturizing, smoothing and has a very good sun protection against both, UVB but also UVA rays. The sunscreen is a chemical one but one of the safest on the market. I have tried many high brand lip balms with SPF and most of them use not save sunscreens or/and don't protect against UVA, also they are drying. But not this one. I use it alone and under my lipsticks/lipglosses.
